实例

例子 1 - 面向对象风格

从结果集中获取行：

<?php
$mysqli = new mysqli("localhost","my_user","my_password","my_db");

if ($mysqli -> connect_errno) {
  echo "Failed to connect to MySQL: " . $mysqli -> connect_error;
  exit();
}

$sql = "SELECT Lastname, Age FROM Persons ORDER BY Lastname";

if ($result = $mysqli -> query($sql)) {
  while ($row = $result -> fetch_row()) {
    printf ("%s (%s)\n", $row[0], $row[1]);
  }
  $result -> free_result();
}

$mysqli -> close();
?>

例子 2 - 过程式风格

从结果集中获取行：

<?php
$con = mysqli_connect("localhost","my_user","my_password","my_db");

if (mysqli_connect_errno()) {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
  exit();
}

$sql = "SELECT Lastname, Age FROM Persons ORDER BY Lastname";

if ($result = mysqli_query($con, $sql)) {
  // 逐行获取
  while ($row = mysqli_fetch_row($result)) {
    printf ("%s (%s)\n", $row[0], $row[1]);
  }
  mysqli_free_result($result);
}

mysqli_close($con);
?>
